SMOKING PIPE.

Application flledlarch 26, 1925. Serial No. 18,526.

To all whom it may concern.-

Be it known that I, CHESTER C. DOTY, a citizen of the United States,residing at Lexington, in the county of Fayette and State of Kentucky,have invented certain new and useful Improvements in S mo king Pipes, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to smoking pipes, and particularly to those pipeswhere-in separate ducts are provided for the smoke and for the saliva.

One of the objects of the present invention is to provide meanswherebythe saliva may be kept-entirely out of contact with the tobacco, andwith means whereby the saliva will not be drawn into the mouth alongwith the nicotine.

A further object is to provide a device of this character wherein thebase of the bowl is removable to permit the insertion of a saliva andnicotine-receiving chamber which, when it becomes foul, may be readilythrown away and permit the introduction of another device of thischaracter.

A still further object is to provide a device of this character whereincool and fresh air may be admitted into the pipe below the tobaccotherein and be drawn into the mouth along with the tobacco smoke, thuscooling the smoke and adding to the enjoyment of the pipe.

Other objects have to do with the details of construction andarrangement of parts as will appear more fully hereinafter.

My invention is illustrated in the accompanying drawing, wherein aFigure 1 is a longitudinal sectional view of a pipe constructed inaccordance with my invention;

Figure 2 is a perspective view of the bowl of the pipe with the bottomof the bowl and the interior chambers removed;

Figure 3 is a perspective view of the nicotine chamber removed from thepipe,

Figure 4 is a perspective view of the duct which extends through thesaliva and nicotine chamber and by which air is carriedinto the airchamber below the bowl;

Figure 5 is aperspective view of the perforated plate which constitutesthe upper wall of the air chamber;

Referring to this drawing, designates the bowl of the pipe, which bowlmay be space between the shoulder 17 and the of any suitable styleor'construc-tion and which is preferably madeof wood, this bowl havingthe wooden stem 11. Engaging with the stem 1l is the bit 12 having theusual mouth piece 13. The bit and the stem are formed to provide alongitudinally extendmg upper duct 14 whereby smoke is drawn from thebowl 10 into the mouth of the smoker, and 15 designates a duct extendingthrough the stem and thro h the bit and intersecting the duct 14: at t emonth, this duct being designed to carry saliva down into the lowerportion of the ipe bowl. The

lower portion of the pipe W1 is recessed at 16 (see Figure 2) and thisrecess is defined by an annular shoulder'17, this shoulder beingdisposed between the openings of the ducts 14 and 15.

The lower end of the bowl is normall partially closed by means of a cap18 which has upwardly extendin marginal flanges interiorly screw-threadto fit the exterior screw-threads. -19 on'the bowl of the pipe. This capis annular in form to provide a central aperture 20. Disposed within theca 18 is a circular casing 21 which may b2 made of metal, bakelite orany other suitable material but which is relatively thin and light, thiscasing having a peripheral wall and upper and lower walls 22 and 23.Both of these walls have a central aperture 2 1 which, when the casingis in place, coincides with the aperture in the cap 18, and disposedthrough these apertures 24 is an air duct 25 also made of metal andwhich preferably is soldered or otherwise formed ntegral with the upperandlower walls 22.

and 23.

Preferably the bottom of the cap 18 is counterbored around the recess 20to. receive the lower end of this member 25, as shown in Figure 1. Theupper end of this member 25 is almost closed save for a central,relatively small perforation 26 which opens into the space above theupper wall 22. This member 25, it will be seen, extends entirely throughthe saliva chamber 27 which is constituted by the case 21. The margin ofthe wall 22 rests againsta gasket 28 disposed against the shoulder-17,and preferably mounted upon the upper wall 22, as by the feet 29, is aperforated disk 30 which is perforated with a large number of fine holessmall enough to prevent the tothis disk is, of course spaced by the feet29 from the wall 22 of t- 'e It is desi edthat the disk and the salivachamber s all be removable thro h the base of the pipe as a unit orinsertib e through the base of the pipe as a. unit. The duct 14 opensinto "the space between the .wall 22 and the perforated disk 30 but theduct 1o is adapted to register with a perforation 31 formed in the sidewall of the casing 21.

In order to prevent the casing 21 from being inserted so that thisperforation 31 W111 not align with the duct 15, I preferably form thecasing with a slight rib or lug 32 disposed, as illustrated, oppositethe perforation 31, though it might be disposedm any ortion, and formthe lower portion of the bowl with a longitudinally extending'recess 33within which this rib is disposed so that whenever the rib 32 isdisposed in this recess 33 the aperture 31 is in register with theaperture. 15.

' The smokingpipe is, of course, used 1n the same manner as any ordinarypige and by filling the bowl with tobacco an the tobacco. The fumes fromthe tobacco are drawn down through the perforated dlsk 30 and outthrough the smoke flue 14. Cool air is also drawnup. through the duct 20and through the aperture 26 in this ductand v as "the pipe will notclog.When thechamber into this-smoke coolingchamber formed between the disk30 and the plate 22. Any saliva which may escape from the mouth passesdown thelower duct 15 .and collects within the chamber 27.: Inasmuch asit does not comei-n contact withlthe tobacco at all,

27 'is filled or has become in'such condition that the smokin of. thepipe is unpleasant, the cap 18 mayhe readily removed and the casing 22withthe disk 30 and the air duct 25 taken out and thrown away and newparts inserted.

It is designed that these parts 21, 25 and 30 shall be connected to eachother as a unit and all these should be of very'light and relativelycheap metal so that they may be readily cast aside and new partssubstituted therefor, making the pipe fresh and new without rendering itnecessary to clean out the pipe and cut it out, which renders the pipehot and unpleasant to smoke. A pipe of the character described is simpleto make, is cool to smoke, and is sanitary. It is ob vious that theprinciple of the device may be applied to pipes of different styles andI do not wish to be limited to the particular style of pipe which isillustrated-in thedrawings. The purpose of the gasket 17 is to. preventsaliva from passing upat the junction, of the duct 15 with the recess 16and over the top of the casing 21 and thus into the smoke duct 14,- andthis casing 21 is held firmly in place by the cap 18. It will be seenthat I saliva chamber.-

igniting have' provided a pipe with a smoke-accumu lating and coolingchamber which so arates the smoke from the saliva and nicotine and"that-in this pipe the nicotine and saliva are stored separately andthestorage chambe'r formed by the casin 21 may-be thrownaside when itbecomes 0 ensive. v I

It will be' seen also that the perforated disk 30 prevents thetobaccofrom coming in contact with thesmoke flue 14 and provides, therefore, amuch freer smokingpipe where the smoke is cooled before assing into theduct 14, and that with this pipe tobacco will not become moist andcaused to plentyof access to the ducts 14 and 15 to permit these to bethoroughly cleaned. Furthermore, the aperture 26.will permit cool air topass into the interior of the ipe and thustend to keep the tobaccoalight and burning. 7

As before stated, I do not wish to be pipes nor to the material of thepipes; Preferably the parts 10 and 11 and the cap 18 will be made ofwoodas, for instance, cherry or briar. Preferably a gasket 34 will bedisposed bet-ween the cap and the lower end of the bowl,'as shown inFigure 1, so as to prevent any possible passage of air around the capand into the saliva duct 15.
